Abstract (en)
A collapsible structural member has been provided in which substantially identical modules made up of metal or plastic are threaded on a tensioning member such as a cable and are movable relative to each other in the collapsed condition of the beam and are brought together into a condition where adjacent modules are locked together to form a rigid construction when the beam is in its erected operating condition. The beam is changed from its erected condition to its collapsed condition by relaxing the tensioning member or cable.
